摘要： A product of the formula (I) in which n is a number from 2 to 14; the radicals R1 are for example hydrogen or C1-C8alkyl; R2 is for example C2-C12alkylene; the radicals A are for example C1-C8acyl; the radicals B are independently of one another —OR3, —N(R4)(R5) or a group of the formula R3, R4 and R5, which are identical or different, are for example hydrogen or C1-C18alkyl, or —N(R4)(R5) is additionally a group of the formula with Y being —O—, —CH2—, —CH2CH2— or >N—CH3; X is —O— or >N—R6; R6 is for example hydrogen or C1-C18alkyl; R is preferably a group of the formula with the proviso that in the individual recurrent units of the formula (I), each of the radicals B, R, R1 and R2 has the same or a different meaning. The indicated product is useful as light stabilizer, heat stabilizer and oxidation stabilizer for organic materials, in particular synthetic polymers.
